If you don't have one of these devices, then it might be a rather difficult challenge to get your card working with the bttv driver because there are a number of parameters (set in drivers/media/video/bttv-cards.c) to set for each card and they tend to be different for each card and learning what those parameters need to be for each card is not trivial. Sometimes you must run your video software in windoze as well as some monitoring software like BtSpy in order to determine the correct hardware settings used in windoze and then use that information to modify bttv-cards.c and create a new card= entry for your card. Make sure you post your findings here and on the video4linux mailing list (video4linux-list@redhat.com) if you do that. You could also try loading the bttv module with the card= parameter set to each one of the cards listed above just to see if you'll get lucky and find one that works for your card. Again, if you are successful, then share your results with the rest of us via this wiki and the list.
